To all whom it may-concern:

Be it known that'I, FREDERICK L. ALLEY, a citizen of the United States, residing at Sydney, New South Wales, Australia, have invented certain new and useful Improvements in Shoe-Sewing Machines; and I do hereby declare the following to be a. full, clear, and exact description of the invention, such as will enable others skilled in the art to to which it appertains to make and use the same.

The present invention relates to shoe sewing machines and more particularly to the type of shoe sewing machines known as welt 15 and turn machines.

In welt and turn shoe sewing machines as now-commonly built, the work is fed by a member which engages the channel of the insole and is moved 'n the direction of the feed'by longitudinally moving the feed shde and is held in engagement with the work during the work feeding movement .of the slide. 'Insome machines this channel engaging member is a feed point or awl. In

other machines it is a channel guide. And in still other machines and particularly in the machine shown in the drawings two channel engaging. members, vizi a feed point and a channel guide are employed to feed the work. After the needle has penetrated the work the channel engaging member or members are released from the work and moved along the line of feed in preparation for the next feeding movement. A back rest is provided to bear against the upper of the lasted shoe to position the shoe with reference to the needle. When the needle is being retracted through the work to draw back a loop of thread, the back rest is locked in position against the shoe. During the feeding movement when the needle is out of the work the back rest is arranged to yield at right angles to the work so that it may adjust itself to the work for the next suceeeding stitch forming operation. During the feed theshoe is dragged over"the yielding back rest which exerts a frictional drag on the work in opposition to the feeding movement.

With the object of more easily and surely feeding the work, one feature of the present invention contemplates a back rest which is moved forwardly along the line of feed during the feeding movement of the work.

When'the welt and turn machine is used for sewing welts, a welt guide is provided to position the welt against the lasted insole and upper. In the usual type of welt and turn machines the Welt guide is mounted on a slide and is retracted from the work durmg -the feeding movement. movement of the work acts to pull the welt through the welt guide to measure the length of the welt for the next succeeding stitch. The work is therefore during its feeding movement not only subjected to the frictional drag of the back rest against the upper but also to the resistance of the welt guide to movement of the welt through it.

W 1th the object therefore of more easily and surely feeding the work when a welt is being sewn, another feature of the present invention contemplates a welt shoe sewing machine in which both the back rest and the welt guide move forwardly along the line of feed during the feeding movement to assist in feeding the. work.

Certain other features of the present invention relate to improved constructions, combinations and arrangements of parts hereinafter described, the advantages of which will be apparent to one skilled in the art from the following description.

In the drawings the preferred embodiment of the invention is illustrated in connection with the well-known Goodyear welt and turn machine which is illustrated and described in the patent to French and Meyer No. 412,704, October 8th, 1889, this sewing machine of French and Meyer being provided with the thread tension releasing device of La Chapelle No. 488,505, December 20, 1892, as is usual in the present commer cial type of machine. It is to be understood, however, that the invention is equally applicable to other types ofsewing machines, and that it can be otherwise embodied without departing from the spirit of my invention.

Referring to'the drawings, Figure 1 is a front elevation of the head of the machine embodying the preferred form of my invention; Fig. 2 is a side elevation taken partly in section looking from the right-hand side of the machine; Fig. 3 is a side elevation taken partly in section looking from the left-hand side of the machine; Figs. 4 and 5 are sectional views taken on the line XX of Fig. 2; Fig. 4' indicating the position of the parts as the work is about to be fed forwardly, and Fig. 5 indicating their position The forward the looper arm; 1F ig. is a top view partly in section showing the mechanism for operating the thread finger; Fig. 11 is a top view of the detached back rest and its slide bar; and Fig. 12 is a View showing a vertical section of the welt guide.

Referring to the drawings, 1 indicates generally the frame of the machine in which is journaled the driving shaft 2 which bears the cam wheels for actuating the various stitch formin means.

3 indicates the feed-point or awl, and a the channel guide, both of which are carried by the longitudinally reciprocating feed slide 5, and given a motion toand from the work by the cam-operated levers 6 and 7 respectively.

8 indicates the curved hook needle operated by suitable levers and cams, and 9 indi-' cates a take-up which cooperates with the other usual thread rolls in controlling the supply of thread to the needle and the work, which is shown as the insole l0 and upper 11 of a lasted shoe to which is being sewn a welt 12. At the left of the machine is shown the link 13 which is broken away at its lower portion, and which is employed to operate a thread tension release upon the reverse rotation of the operating shaft, the notch 14.- in the operating shaft engaging the ratchet tooth or catch 15 upon the link and depressing it when the direction of rotationof the operating shaft 2 is reversed. The forward direction of rotation of the shaft 2 is indicated by the arrows in Figs. 2 and 3. The above parts are constructed and arranged to operate in a Well-known manner, substantially as set forth in the French and Meyer and the La Chapelle patents, and further description thereof is considered unnecessary.

The welt guide 16 is pivotally mounted upon the forward end of a sliding bar 17 which is normally held in its forward position by a helical spring 18 to hold the welt guide in engagement with the work. The forward movement of the slide bar 17 under the action of its spring is limited by a shoulder 19 formed u on the slide bar which is adapted to stril e against the adjustable screw 20 mounted in a fixed part of the machine frame. By adjusting the screw 20 the forward limit of the movement of the welt guide may be varied at will. The slide bar 17 is normally locked in its forward position by the engagement of.a locking pawl 21 with the ratchet teeth 22 formed upon the slide bar. The locking pawl 21 is carried upon one arm of a cam-operated lever 23 which is actuated by a cam roll 24 running in a cam path formed in the side of a cam wheel mounted upon the driving shaft 2.

This cam path is so timed with relation other parts of the machine that the cam roll 24 will actuate the lever 23 to raise the pawl 21 against the tension of the spring 25, which normally holds it in engagement with ratchet teeth 22, and release said locking pawl from the bar 17 while the work is fed forwardly and the needle penetrates the work. This by a finger 27 which is rigidly carried upon a shaft 28 journaled inthe machine frame.

The outer end of the shaft 28 is provided with a slotted arm 29 which is engaged by a pin on the link 13 when said link is depressed by the engagement of the notch 14- with the tooth 15-when the operating shaft is turned in a reverse direction. The downward motion of the link 13 is communicated to the slotted arm 29, turning the shaft 28 and moving the finger 27 against the pin 26, thus retracting the sliding bar 17 together with the welt guide 16. The notch let is so positioned upon the-cam shaft with respect to the cam which operates the release lever 23 that the slide bar will be retracted on a reverse rotation of the shaft at the time part of'each cycle of the stitch forming operation. This retraction may be imparted to the sliding bar 17 by the engagement of a swinging pawl 30 with the ratchet teeth 31 carried upon the sliding bar. The pawl 30 is normally held in "engagement with the ratchet teeth 31 by a spring 32, and is given a swinging motion back and forth along the line of the slide bar by a lever 33, upon whose end said pawl ispivotal'ly mounted. The lever 33 receives an oscillatory motion from the cam roll 34 carried by the upper end thereof and running in a cam path formed in the side of a cam wheel carried by the shaft 2. When the pawl 30 is swung backwardly, it engages the teeth 31 and 17 to freely move forwardly under the tension of the spring. To vary the point of engagement and disengagement of the pawl 30 from the ratchet teeth 31 and thus determine the amount of retractive movement that it imparts to the sliding bar 17, the

shield is adjustable upon the machine frame and held thereto b a clamping screw 36 enga ing through a s 0t 37 in the shield piece. he position of the ratchet 31 beneath the pawl 30, when the welt guide is pressed against the work, is determined by thickness of the work engaged. The pawl 30 has a fixed amount of backward swing and upon its en a ement with the ratchet teeth moves the s i ing bar back a predetermined distance regardless of thickness of the work.

The welt guide 16 is mounted upon the forwardly extending arm 38 of a lever 39 which isivotally'mounted to oscillate in a horizonta plane about a fulcrum in 40 on an oil-set bracket 41 which is rigid y securedto "the forward end of the sliding bar 17. The sliding bar 17 has a spline 42 engaging in a suitable groove in the bracket 41 and an adjustment between the bracket and sliding bar is secured by a-clamping screw 43 engaging through a slot 44 in the slidin bar. The forwardly extending arm 38 is o set to the right to some extent so that when the lever 39 is oscillated about its ivot the welt guide 16 carried upon the en of the offset arm will approach the work when it is swung to the left during the feeding of the work, and will be retracted from the surface of the work when it is swung back along the-line of feed to the right. As is common in this type of machines, the roll of welting is laid on a bench or table at the right of the machine, and is drawn over a hook 16, passing somewhat forwardly to the welt guide and the shoe. The swinging movement of the welt guide to the right and to the rear is thus in substantially the same plane in which the welt normally lies in its approach to the work. The lever 39 has a rearwardly extending arm formed with a recess 45 in which issjournaled a cylindrical block 46, which is also free to slide longitudinally in the recess. The cylindrical block 46 is transversely bored to form a journaled and a sliding bearing for the end of a pin 47 which extends forward from the lower end of a lever 48. The lever 48 is adapted to be oscillated in a vertical plane about a fulcrum 49 which secures it to the machine frame. The swinging motion of the pin 47 is communicated through the sliding block 46 to the lever 39. The sliding engagement of the block 46 in its recess and the journaled and sliding engagement of the pin 47 in the block 46 allows the motion of the pin 47 which is swung from a pivot 49 upon a fixed partof the machine frame, to be. communicated to the welt guide lever which-is pivoted upon the sliding bar 17 which is movable relatively to the machine frame on a line inclined to the horizontal. The lever 48 re- 'reives its oscillatory motion through a link 50 which is pivoted at 51 to the upper end of said lever. The other end of the link 50 is pivoted at 5 2 to the forwardly offset arm 53 of a lever 54 which is pivotall mounted to oscillate about a pin 55 carried y the machine frame.

point at which it applies its force to the link g 50 is offset forwardly from the lever. The

' lever 54 receives its oscillatory motion from areciprocating link 59. The end of the link 59 is received b the bifurcated end of a sliding bar 60 w ich actuates the swinging back rest to be hereafter described. A pin 61 pivotally connects the link 59 to the bar 60. The ends .of the pin 61 extend laterally from the sliding bar 60 and-are journaled in blocks 62 which are slidably mounted in recesses 63 formed in the bifurcated lower end of the lever 54. The sliding engagement of the blocks 62in the recesses'63 allows the reciprocatory motion of the end of the link 59 to be transformed into an oscillatory niotion of thelever 54. The link 59 receivesits 'reciprocator motion from a lever 64 to the lower end 0 which it is pivotally connected by a pin 65 adjustably held in a curved slot 66. The lever 64 is given an oscillatory m0:

tion by means of a cam roller 67 which ru in a cam path 68 formed in the periphery of a cam wheel carried by the driving shaft 2. The lever 64 has an oscillatory motion of a 'fixedamount, but the amount of movement which it communicates to the link 59 may be varied by adjusting the position of the pivot pin 65 in the curved slot 66 at the lower end of the lever 64. The motion of the lever 64 is thus communicated through the connecting chain of links and levers to the welt guide 16 which is positively oscillated about its pivot togive it am'otion in the direction of feed and toward the surface of the work, and a motion backwardly along the line of feed and away from. the surface of the work. Since the welt in its approach to the shoe lies in a plane which is slightly in clined to the surface of the shoe, the movement of the welt guide is in substantially the same plane in which the, welt normally lies, so that when the welt ide is moved the welt guide is moved forwardly the welt will be moved against the surface of the work and slightly gathered thereon. The

degree to which the welt is athered against the shoe may be varied t y varyi the amount of movement imparted to the welt guide. It the welt guide he moved hackwardly to measure oil? a length of welt equal to the distance that the shoe is fed, the welt will he merely laid against the shoe and not gathered. However, it the welt guide he moved loackwardly to measure ed a length of welt greater than the distance that the shoe is fed, the forward movement of the m welt guide will cause it to move in the direction of feed slightly faster than the shoe, and will crimp or gather the welt against the shoe. which it is desired to give to the welt may be determined ior any particular machine by suitably proportioning the welt guide mechanism.

lln order that the welt shall he firmly held against the shoe during the retractive .movement of the needle, a forwardly projecting work-engaging finger 69 is formed on the bracket 41 to which the welt guide is pivoted, which prevents the welt from heing drawn away from the shoe lay the hackward pull of the needle through it or by the measuring movement of theatrelhguide.

Since the ofisetting of the welt guide to one side of its pivot point causes its oscillatory movement to move it forward against the surface of the work and to retract it from the surface of the work, it is possihle to entirely dispense with the retracting pawl 30, together with its operating means, for withdrawing the sliding bar, and thus considerably simplify the construction of the machine. @r, it it is so desired, the pivoted welt guide may be used in conjunction with the pawl retracted slide her, as illustrated in the present construction. It is to l he understood, however, that the use of the pivoted welt guide mounted upon a forwardly spring-pressed slide bar which is not provided with retracting means, or the use of the welt guide pivoted directly to the 66 frame of the machine, is contemplated within the spirit of the invention.

The back rest 70 is formed on the front of a hell crank lever 71 which is pivotally mounted at 72 upon the ofiset forward end otl off a sliding her 73. The work engaging face of the back rest is curved on the arc of a circle with the pivot point 72 as a center so that as the hack rest oscillates about its pivot, the surface of the hack rest is swung C3 along the direction or feed without move ment of approach to or recession from the work. 'l he sliding bar 73 is pressed forwardly hy a spiral'spring 7a and is locked in its forward position during a part of the Q 3 stitch forming operation by a pawl 75 and ratchet wheel 3'6. The construction and up oration of said spring and said har locking mechanism is suhstantially the same as that disclosed in the ahove-mentioned French 65 and Meyer patent. The bell crank lever 71' The amount of gathering, it any,

is given an oscillatory motion about its pivot 72 by a link 77 pivotally connected thereto at 7 8. The other end of the link 77 is pivoted at 79 to one arm of a bell crank lever 80 and receives a reciprocatory motion from the oscillation of said hell crank lever. The loell crank lever 80 is fulcrumed frame at right angles to the direction in which her 73 is slidahle. The motion imparted to the lolock 82 by the reciprocation or its containing loox 83 oscillates the lever 80. The sliding engagement of the lolock 82 in the hon 83 allowsthe reciprocatory motion of the bar 60 to be transformed into an oscillatory motion of the lever 80, and also provides for the transfer of motion hetween these parts regardless of the position of the sliding bar 73 in the machine, since it is evident that motion will he imparted to the lolock 82 in whatever place it may chance to he in the her due to varying position of the sliding bar 73 to which lever 80 is fulcrumed. The sliding har pivotally receives in its bifurcated end the link 59 which 1m arts a reci rocator nio- Q tion thereto and which also as nreviouslv 9 9 J descrioed, actuates the welt giude mecnaand its actuating lever 64: is communicated through the alcove described system of lir and levers to the hack rest 70, which is tins given a motion to and fro along the line of feed of the work. The timing of the cam path (38 is such that both the welt guide and the hack rest will swing along with the work and assist the feed point and channel guide when they feed the work in preparation for a stitch, and that motion of the back rest and welt guide haclrwardly along the line of feed of the work to position the back rest and welt guide in preparation for the next feeding movement and to draw the welting strip through the welt guide, will take place while the work is positively locked in position by the penetration of thneedle therethrough.

The welt guide is illustrated in detail in Fig. 12. The upper wall 84: oi" the welt receiving aperture is formed directly on the welt guide lever 39 and has a rib 85 engage in the groove in the welting strip 12. llhe front and lower walls of the welt receiving aperture are formed of a guide plate 86 whose two ends have slots 87 for reception of clamping screws 88 by which it is adjustahly held to the arm 39. The clamping screws and slots allow the guide plate 86 to be adjusted to vary the depth of The motion of this common link 59 adjustment of the pin'106 in the slot 105" allows the amount of oscillation given to thethe welt receiving aperture to accommodate for welts of different thickness. The back wall of the welt guiding aperture is formed by a gage'piece 89.

The thread finger is formed. of two thread-engaging prongs 91 and 92 carried upon the end of an arm 93 which projects radially from a shaft 9 1. The shaft 9-1 is slidably received in 'a bushing 95 whichis held in the bracket 96 of the machine frame by a clamping'nut 97 and held against rotation by a set screw 98." The interior of the bushing 95 is provided with a spiral slot 99 in which is engaged a pin 100 projecting from the shaft 94. When the shaft 94 is reciprocated, the pin 100 and the spiral slot 99 give the shaft 94 a motion of rotation as well as reciprocation, and move the thread finger 90 in a spiral path. The forward motion of the thread finger is in the direction of the projection of the prongs 91 a) 1d 92 so that the thread is engaged between tile prongs. The end of the shaft 94: opposite to the thread finger arm is formed with an en-- larged head 101 which is received in a recess 102 formed in the lower end of a bell crank lever 103 pivoted at 104 toJhLhracket 96. The oscillatory motion of the bell crank lever 103 gives to the shaft 94: a reciprocatory motion, the ball and socket connections allowing the head 101 to both slide and turn in the socket 102. The other arm of the bell crank lever 103 is slotted at 105 and has adjustably clamped in said slot a pin 106 to which is pivoted one end of a link 107. The other end of the link 107 is pivotally held at 108 on a sliding block 109 whose reciprocation oscillates the bell crank lever 103. The

bell crank lever by the reciprocation of the block 109 to be varied. The block 109 is slidably held in a suitable box 110 which is rigidly mounted upon the machine frame. The sliding block 109 bears upon its upper end a roller 111 which is received in a cam path 112 out in the side of a cam roller 113 mounted upon the driving shaft 2 of the machine. The timing of the cam path 112 is such that the thread finger 90vwill engage the thread and carry it behind the polnt of the needle 8 after the needle has penetrated the work.

I The looper'eye 114 which cotiperates with the threadfinger in threading the barb of the needle is carried on a block 115 slidably mounted in the bifurcated lower end 116 of the looper lever 117. The lopper lever 117 is fulcrumed near its center on the pivot pin 118 held in a bifurcated head 119. The head .119 is pivotally mounted upon the machine frame by a pin 120 engaging. in a suitable socket formed in the machine frame. This arrangement gives the looper lever 117 freedom to swing in all directions about the oint 118. The lower arm of the lever 117 is ongitudinally recessed to receive asliding bar 121 to whose lower end is rigidly secure the block 115. The upper end of. the bar 121 has secured thereto a head 122 which is laterally recessed at 123 to receive a block 124 which is free to slide laterally in'the recess.

The block 124 is pivotally mounted at 125 eye outwardly, t e fulcrum 127 of the bell crank lever 126 will also move outwardly from beneath the head 119. The gear teeth 128 are, however, held by their meshing engagement with the gear teeth 129 sothat the bell crank lever 126 is turned and the block 124 moved downwardly, which imparts to the looper eye a motion downwardly as well as "forwardly. The looper lever 117 receives its motion from a cam wheel 130 mounted on the driving shaft of the machine. A roller 131 borne upon the upper end of the lever 117 is received in a cam groove 132 cut in the periphery of the cam wheel 130 and oscillates the lever 117 about the axis of the pivot pin 120. The upper end of the lever 117 also bears two rollers 133 which bear against peripheral cam surfaces 134 formed on the periphery of the cam wheel 130. The cam rollers 133 give the lever 117 a movement of oscillation about the pin 118. The cam rollers 133 are held in, engagement with peripheral cam surfaces 134 by a spring 135 which is received in a suitable recess formed in a bracket arm 136 of-the machine frame. One end of the spring 135 is held against an adjusting screw 137 while the other end presses downwardly against a sliding block 138 in which is formed a socket 139 receiving one end of a ball-ended link 140 whose other end is received in a similar socket 141 formed on the top of the lever arm 117. The formand timing of the cam paths which actuate the looper lever is such that after the thread finger has engaged and carried a bight of thread behind the point of the needle, the

and the reciprocatory movement of the bar 121 cause the looper eye 11% to travel about the barbed end of the needle in a curved path lying in a plane approximately normal to the end of the needle, so that the bight of thread between the thread finger and looper is laid in the needle barb more nearly at right angles to the needle shank and the needle does not need to be projected as far forwardly as would be necessary if the looper eye did not move relatively to the looper lever, in which case the looper eye would move forwardly in a curved path lying in an approximately horizontal plane.

The operation of the machine, particularly that of the improvements in which the present invention is embodied, is as follows:

Starting in the position shown in Fig. 4, in which the feed point and channel guide have just engaged the work, the feed po nt and channel guide are moved along to feed the work. Simultaneously with the movement of the feed point, the back rest and welt guide are swung along in the direction of feed of the work, the welt guide moving into engagement with the work and pressng and gathering the welting strip against the shoe. The parts have assumed the position illustrated in Fig. 5. The needle now descends and pierces the work, as shown in Fig. 6. After the needle has pierced the work, the feed point, channel guide, 'back rest and welt guide are moved backwardly along the line of feed in preparation for the next feeding stroke, as shown in Fig. 8, the welt guide measuring oil the welt for the next stitch. After the needle has pierced the work and is held in its forward position, the thread finger moves to the right in a spiral path, catching the thread between its prongs and taking a bight of thread across the plane of oscillation of the needle above the horizontal portion of the needle shank and behind the barbed end of the needle, the parts assuming the position shown in Fig. 7. T he 'looper now moves in a curved path forwardly in front of the needle and downwardly, laying the thread across the needle and pulling it into the needle barb, the parts assuming the position shown in Fig. 8.. After the needle is threaded, it is retracted and the feed point and channel guide a ain engage the work, as shown in Fig. i, w ich (-on'ipletes one cycle of the stitch forming and work feeding operations. Since the thread linger moves behind the needle and the motion of the looper is forwardly and along the path curved only sufficiently to lay the thread against the barb of the needle,

the needle on its retraction will draw the thread through the work in an untwisted loop. as illustrated in Fig. 4.
